Rangers manager Mark Warburton has told The Sunday Post that he thinks he should have attacked more against Celtic last month.

In September, Rangers took on Celtic in a league game for the first time since 2012, and fans were hoping for a repeat performance of the Scottish Cup semi-final win over the Bhoys in April.

However, Celtic – reinvigorated under new boss Brendan Rodgers – ran riot at Celtic Park, hammering Rangers 5-1 with a Moussa Dembele hat-trick as well as goals from Scott Sinclair and Stuart Armstrong.

On Sunday, the two sides meet yet again, this time in the Scottish League Cup, with a place in the final up for grabs.

Rangers will be desperate to exert some revenge on Celtic after that hammering last month, and manager Mark Warburton has been discussing his mistakes from the first game.

Warburton told The Sunday Post that, if he could change one thing from the game at Celtic, it would be to play on the front foot more, suggesting that Rangers may look to adapt tactically by attacking a little bit more on Sunday.

Warburton suggested that the Rangers players were lacking some self belief, and wants his players to play with more confidence.

The Rangers boss did though add that he tried to play too many new players against Celtic last month, and he'll no doubt be hoping that those players have bedded in ahead of Sunday's clash.

“If there was one thing I would change from the last Celtic game, it is that we should have been playing more on the front foot,” said Warburton. “We went into that game lacking a little bit of self-belief. We went into the Scottish Cup semi-final last season with no lack of belief at all, and absolute confidence in what we were going to do. It has to be that way.”

“New players arriving and trying to bed them in weakens that self-belief because you haven’t built it yet. I’ve put my hand up about this season’s first game against Celtic, and said the midfield was Joey Barton, Niko Kranjcar, Josh Windass – three new players. Philippe Senderos was playing his first game other than 90 minutes against Linfield, and Joe Garner hadn’t long arrived. So we had half of a new team, and maybe in hindsight there were too many changes,” he added.
